It's used when serializing: things with _moz_dirty are prettyprinted even if the serialization is trying to preserve the original whitespace layout of the HTML in general.
The fact that it's an actual content attribute is a bug dating back to when there was no other good way to associate state to an element in Gecko; we just need to fix that. See https://bugzilla.mozilla.org/show_bug.cgi?id=459212
